Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a water tank for a shower tester used for waterproofing test of textiles.

[0002]

[Prior Art]

 The rain test method, that is, the shower test method is described as a reference in the waterproofness test method for the textile products specified in JIS L1092-1986, and the simplest device for carrying out this test method is shown in FIG. The device of the mechanism is used.

This device stores a fixed amount of water (103) in a tank (102) supported by a support (101), and a fixed amount of water is supplied from the spray nozzle (104) to a cloth (105) to be inspected by this water pressure. A water pipe (107) having a water quantity adjusting valve (106) is replenished so that the water level in the tank (102) is always maintained at a fixed position. It is what you have done.

In the method specified in JIS L1092-1986, however, a filter paper (108) specified in JIS P3801 is applied to the back side of the cloth to be inspected (105), depending on the amount of water absorbed therein. The waterproof performance of the cloth to be inspected (105) is evaluated. In order to make the inspection result highly accurate in such an inspection method, the amount and pressure of water discharged from the spray nozzle (104), that is, the tank (102). It is necessary to keep the water level inside in place at all times.

In the device shown in FIG. 2 described above, such requirements are satisfied by adjusting the opening degree of the water guiding amount adjusting valve (106) provided in the water guiding pipe (107). The valve for adjusting the amount of introduced water (106) is opened so that the amount of water corresponding to the amount of water discharged from (104) is always introduced into the tank (102).

However, the water pressure applied to the water quantity adjusting valve (106) is slightly affected by the open state of another water stop plug (not shown) connected to the water supply source (not shown). Even if the opening of the water flow rate adjustment valve (106) is kept constant, the amount of water supplied to the tank (102) is not constant and sometimes fluctuates, causing the tank (102) to change during a long shower test. There is a problem that the water level inside rises and falls and the amount of water in the spray nozzle changes, reducing the accuracy of the waterproof test.

In order to solve such a problem, Japanese Utility Model Laid-Open No. 1-135360 discloses a double pipe structure of an inner tank and an outer tank surrounding the inner tank, which is provided at the bottom of the inner tank for storing a predetermined amount of water. Install a water pipe with a water flow control valve and a discharge pipe connected to the spray nozzle, fix multiple level valves to the peripheral wall of the inner tank, and provide a drain pipe for overflow at the bottom of the outer tank. A water tank for a shower tester, which is characterized by that, has been proposed.

However, the water tank of such a shower tester can keep the water level constant at a certain height, for example, 3 feet or 6 feet, but many level valves are used to keep the water level constant at an arbitrary height. There is a problem that it needs to be fixed and cannot be provided industrially at low cost.

[0009]

[Problems to be solved by the device]

 An object of the present invention is to provide a novel tank structure which has a simple structure but completely solves the above problems and keeps the water level in the tank at a predetermined value during a shower test.

[0010]

[Means for Solving the Problems]

 The present invention has the following configuration in order to solve the above object. That is, a main body tank and an auxiliary tank communicating with the main body tank are provided, the auxiliary tank is movably supported in the vertical direction, and a discharge pipe connected to a spray nozzle is installed at the bottom of the main body tank that stores a predetermined amount of water. However, a drainage port for overflow is provided in the upper part of the auxiliary tank, and a water conduit having a valve for adjusting the amount of water introduced is fixed to the auxiliary tank.

[0011]

[Action]

 In the present invention, since the main body tank and the auxiliary tank communicate with each other, the overflow drain port at the upper part of the auxiliary tank is moved to a position corresponding to the desired water level, and the amount of water flowing in from the water flow adjusting valve is sprayed. Even if the water pressure applied to the water flow adjustment valve changes slightly, the desired water level can be obtained by slightly increasing the amount of water ejected from the nozzle and letting the excess water flow out from the overflow outlet at the top of the auxiliary tank. In this way, the amount of stored water is maintained.

[0012]

【Example】

 The present invention will be described in detail with reference to the embodiment shown in FIG.

FIG. 1 is a vertical cross-sectional view of a water tank of an embodiment. (1) is a cylindrical body, which is a main body tank supported by a column (not shown), and (2) is similarly a cylindrical body. In the auxiliary tank, both tanks (1) and (2) are connected by a communication member (10) made of a rubber tube. (11) is a column that supports the auxiliary tank (2), and the auxiliary tank (2) is movably supported in the vertical direction by adjusting the holding portion (12) of the auxiliary tank (2). Has been done. (5) shows a discharge pipe communicating with the bottom part (3) of the main body tank (1), and a spray nozzle (4) having a shape specified in AATCC or JIS is fixed to the outlet of the pipe (5). is doing. (9) is a water pipe with a water quantity adjusting valve (8) provided in the auxiliary tank (2), and (7) is drainage water for overflow water delivery provided in the upper part (6) of the auxiliary tank (2). Show mouth.

The water tank of the embodiment has the structure as described above, and the usage state thereof will be described next.

Although substantially overlapping with the above description, in order to obtain a predetermined water level, for example, 6 feet line, the overflow outlet (7) at the upper part of the auxiliary tank (2) corresponds to the water level of 6 feet line. Move to the position, make the amount of water flowing in from the water flow rate adjusting valve (8) larger than the amount of water ejected from the spray nozzle (4), and the excess water flows out from the drain port (7) for overflow by overflow. And discharge it to the outside through the drain pipe (13).

In such a storage state of the water tank of the present invention, even if the water pressure applied to the water quantity adjusting valve (8) changes, the level of the stored water does not change due to the change in the amount of overflow water. Therefore, it is possible to improve the test accuracy by applying a specified amount of water and a specified water pressure to the cloth to be inspected (14) through the spray nozzle (4) and applying the filter paper (15) specified in JIS P3801 to the back side. You can do it.

In the above embodiment, the details of the tank diameter, the spray nozzle size and the like are omitted, but these are naturally in accordance with JIS or AATCC.

[0018]

[Effect of the device]

 Since the water tank for the shower tester of the present invention is designed to move the overflow drainage port to the specified water level line to maintain the water level as in the above embodiment, JIS L1092- As described in 1986 reference, there is no need to adjust the position of the level valve with a screw mechanism, and because the regulated water surface is maintained by the water introduced from the bottom of the tank, there is no water sway, and constant pressure and a fixed amount of water By spraying from a spray nozzle, the problems of the conventional tank described at the beginning are completely solved.
